Information Provision Policies for Improving Farmer Welfare in Developing Countries: Heterogeneous Farmers and Market Selection

We examine the impact of information provision policies on farmer welfare in developing countries where farmers lack relevant and timely information for making informed decisions regarding which crop to grow and which market to sell in. In addition to heterogeneous farmers, we consider the case when farmers are price takers and yet the price of each crop (or the price in each market) is a linearly decreasing function of the total sales quantity. When market information is offered free of charge, we show that (a) providing information is always beneficial to farmers at the individual level and (b) providing information to all farmers may not be welfare maximizing at the aggregate level. To maximize farmer welfare, it is optimal to provide information to a targeted group of farmers who are located far from either markets. However, to overcome perceived unfairness among farmers, we show that the government should provide information to all farmers at a nominal fee so that the farmers will adopt the intended optimal provision policy willingly. We extend our analysis to examine different issues including information leakage, social welfare, precision of market information, and information dissemination via a for-profit company.
